Abstract (en)

[origin: US6635111B1] Known devices for contactlessly guiding or treating continuous lines of material (1) have one chamber (2). A supply device (3) for a gaseous fluid is connected to said chamber (2), which has a gas-permeable wall (4). The outer surface (5) of said wall (4) is embodied as a guide surface for the line (1). According to the invention, the gas-permeable wall (4) is produced from a porous, metal-containing material with open pores which have an average diameter of less than 500 mum, preferably less than 100 mum, especially less than 20 mum. The porous material used for the guiding surface enables the line (1) to glide on a fluid pad of less than 1 mm. The losses of fluid on the surfaces not covered by the line (1) are very low.
